DIRIGIBLE HEADLIGHT.

Specification of Letters Patent.

Patented Jan. 10, 1911.

Application -fi1ed October 22 1910. Serial No. 588,546.

an improved construction designed primar-' ily for motor cars and embodying a pair of pivotally mounted lamp brackets located at the front end of the car-and having individual connections with a pedal-actuated rock shaft, the arrangement being such that the shaft, in question may be rockedin either throw the light fromf direction, so as to both lamps at one side or the other of the road, as circumstances mav require, means being provided, however, for normally maintaining the light beams iii-parallelism with the longitudinal axis of the car.

A structural embodiment of the invention is illustrated in the accompanying drawing, wherein- Figure 1 is a plan view, showing the application of-said invention. Fig. 2 is a side elevation of Fig. 1, with parts in section. F i'g. 3 is a detail view of the rock shaft and the parts connected thereto. Fig. 1 is a perspective view of one of the lamp brackets and its support.

In said drawings, 1 and 2 indicate the two side beams, and 3 and t the front and intermediate cross-beams of the frame of a car of conventional type, and the front portion of the floor of the car.

Adjacent the front end of each beam, and there is bolted or otherwise secured a metal plate 7 arranged, in the present instance, against the outer face; of the beam and formed at its upper edge with a lip S which projects laterally across the top of the beam and constitutes a support for the lamp bracket 9. Said brackets are preferably of the well-known fork type, and the r bases rest upon and are suitably pivoted to the plate lips. These brackets are connected with a pair of opera-ting rods 10 arranged longitudinally of the car frame and extending beneath the floor and the hood, as shown in Fig. 2, whereby they are concealed and their interference with the driving and transmission mechanisms prevented. The-front ends of Improvements in Dirigible Headlights, of

said rods are pivotal v connected to the rear ends of a pair of links 11, the front ends of which hnks are f stened to depending pivot pins 12 secured to the inner ends of the 0 bracket bases. To actuate said operating rods, their rear ends are pivoted to a pair of oppositely-extending crank arms 13 and 11 mounted on a transversely-arranged rockshaft 15 that is located in front of the cross-.

beam tand is suitably supported at its ends by the side beams 1 an The arms 13 and 14 are adjustable on the rock shaft, and are designed to be held in the desired position by means of set screws 16 or the like. is also mounted in a similar manner on said shaft a third crank arm 17 provided with a bifurcated outer end herein is pivotally secured the rear end of pitman 18 that car There tends forwardly=from the shaft and is pivoted at -its front end' tothe lower end of a pedal lever 19. This pedal is preferably of the bell-crank type and is pivotally mounted at the intersectionof its two arms betweer a'pair of ears secured to the usual inclined portion .of the floor. Said plate isprovided with a longitudinal slot 22 which re isters with a. similar slot 23 in the floor, as iwill be understood,

20 formed upon a plate 9.180

the lower arm of the pedal eXtending through said slots. The upper or outer pedal arm extendsupwardly and rearwardly toward the drivers seat, (not shown), and its foot plateflat is so curved as to admit. of the pedal direction. The forward ends of the operating rods pass through slots 2-5 in the fri'nt cross-beam 3.

Means is provided for normally holding the rock shaft in a neutral position, i. 0., in such a position that the beams of light from the two lamps mounted on the brackets 9 will parallel the longitudinal axis of the ear, or, in other words, will be cast straight ahead of the car. In the construction illustrated, such means is associated with the rock shaft and is constituted by a leaf spring 26 coiled around said shaft and connected to the same at its inner end,'itsouter end'being fastened to beam 4..

The operation ,of the invention will be readily apparent from the foregoing, and is substantially as follows: Movement of the pedal, either forward or backward, will produce rotation of the rock shaft, and, in consequence,

being readily rocked in either.90

Movement of said rods will, in turn, have the effect of swinging the lamp brackets be simultaneously turned ineither direction, so as to cast their beams in any desired direction and at any desired angle'with respect to the longitudinal axis of the car,'thc

lamps being returned automatically to their normal position by the spring 26, as soon as the pressure upon the pedal is removed.

The device, as a whole, is certain and positive in its operation, and consists of but ew parts, and those of the simplest character, by reason ofwhich fact it may be constructed at an extremely low cost. It may be readily applied to any standard make of car without occasioning re-arrangement of the'mechanism thereof, and when in place will not interfere with the operation of such mechanism. Finally, it is practically entirely concealed, and, hence, cannot of itself render the appearance-of the car unsightly. Between the bases of the lam brackets and the plate lips, a series of anti-friction bear ings 27 may be interposed.

mm as my invention: 1. The combination, with the frame and floor of a car; of a rock shaft arranged transversely of the frame and below the floor; a.

lamp bracket pivotally supported at the front endof each of the side beams of said frame; a pedal for rocking said shaft in .eitherdirection; and a separate connection between each bracket and the shaft,.for turnmg bot-h lamps simultaneously in the same direction when said shaft is rocked.

2. The combination, with the frame and fioor of a car; of a rock shaft arranged transversely of the frame and below the floor; a lamp bracket pivotally supported at the front end of each of the side beams of said frame; a pedal for rocking said shaft in either direction; a pair of links pivotally connected to said brackets; a pair of oppositely-disposed cranks secured to said shaft; and a pair of longitudinal operating rods pivotally connected at their rear ends to said cranks and at their front ends to said links,

for turning both lamps simultaneously in the same direction when said shaft is rocked.

3. The combination, with the frame and floor of a car; of a rock shaft arranged transversely of the frame and below the floor; a

lamp bracket pivotally supported at the front end of each of the side beams of said frame; a pedal pivoted to said floor; a crank secured to said shaft; a pitman connecting said crank and said pedal; a pair of oppositely-disposed additional cranks se-- either direction; a separate connection be tween each bracket and the shaft, for turn-,

ing both lamps simultaneously in the ame direction when said shaft is rocked; and a spring connected with said shaft for nor mally holding the same in neutral position.

5l-The combination, with the frame and floor of a car, said frame including side beams and connecting cross-beams; of a. rdlfshaft arranged below the floor;.a. lam

bracket pivotally supported upon each si? e beam; means for rocking said shaft; a sep-. arate connection between each bracket and the shaft, for turning'both lamps siniultaneously in the same directir-u when said shaft is rocked; and'a spring coiled about said shaft and connected at one end thereto and at the other end to one of said cross-beams, for normally holding the shaft in neutral position.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit.- nesscs.
